What Hits Harder 1 Ohm Or 4 Ohm? Is 2 Ohm Your Best Bet?


Impedance needs to be clarified concerning sound quality and audio equipment. Even if frequency range, power handling, sensitivity, and other factors are hard to understand- nothing beats impedance when it comes to complexity.

It is very puzzling that sometimes people need help understanding what impedance is ideal for them. What hits harder 1 ohm or 4 ohms? This is a common question when purchasing new equipment.

Audio Current Flow: What Hits Harder 1 Ohm Or 4 Ohm?

What hits harder between these two? To make it easy for you to understand, we devised a detailed and thorough guide about impedance. This includes how they work and what you can acquire from different measurements.

This is an easy to comprehend guide that might eliminate your confusion quickly. So, you want to know which one is for you. Continue reading!

Getting to Know More About The Overall Impedance

The most vital question is, what does impedance denote? In short, impedance measures electric circuit resistance. This means that the electricity of a speaker or subwoofer is created once it gets an electrical signal from other components, such as an amplifier.

The electrical resistance or load is called Ohms, which represent Omega (Ω), a Greek letter. This measurement shows the amount of electric load the impedance creates when getting electricity from a receiver or amplifier.

That is why it is vital to choose a speaker or subwoofer with the correct impedance measurement that suits the component output. Most subs or speakers have impedance measurements that range from 1 to 8 Ohms, pasting through 2, 4, and 6 Ohms.

The best thing about Ohms is that they count in reverse. When you put in two 8 Ohms subwoofers measurements each, you will have 4 Ohms resistance rather than 16 Ohms.

If you like to connect two speakers with 8 ohms impedance, each with an amplifier with the exact measurement, you might not be able to do so.

This is because the mishmash of the speaker would provide 4 Ohms, which is lower than what the 4 Ohms amplifier can work with. This low power supply leads your multiple subwoofers or speakers to heat up and automatically switch off.

1 Ohm Impedance Overview

To attain 1 Ohm impedance, you have to connect two or more subs/speakers of low impedance. But ensure you connect them using parallel wiring. This can assist your speakers in reaching 1 Ohm. However, prior to doing that, it is essential to know if the amplifier is able to handle such levels of impedance.

If you are able to attach the amplifier with a 1 Ohm system, perhaps you will attain a good performance from the subs or speakers. Obviously, this will push the amplifier to consume more electricity, so you are likely to get louder and more in-depth audio from the system.

However, the 1 Ohm system is unstable. This occurs as they carry out at the least resistance level, which often puts the amp under stress.

As there is not much resistance to deal with, the subwoofer’s or speaker’s impedance will suck away more power from the amplifier. The less power

If the amplifier cannot handle it, there is a chance of overheating, blowing, or shutting off to avoid further damage. While you attain deeper and louder bass, even with the correct configuration, the stereo system will work unstable and hot.

Aside from that, 1 Ohms system is hard and complex to install. Speakers and amplifiers only reach this resistance of impedance if you have some of them hooked up or if you purchase lower-impedance components that are expensive.


  • Deep bass, in some cases
  • Super loud


  • Costly amps and installation
  • Can harm amps
  • Amp runs hot
  • Not stable sound

4 Ohm Impedance Overview

A 4 Ohm of impedance in a speaker or subwoofer is considered the most common rating available. You can attain this with one component or by connecting two 2 Ohm pieces in series wiring.

4 Ohm impedance is compatible with all types of amps. As for loudness and sound quality, you’ll be astounded. Actually, the sound is clearer and more stable.

Plus, the 4 Ohms system has a lighter sound and a lower electrical resistance. But this makes sure a quality performance without being too low or too high. A superior set of subwoofers and speakers can maximize this configuration.

You will not attain similar loudness, as well as bass depth as with a 1 Ohm speaker; however, it will still manage to do decently well in some cases. The amplifier will not put much pressure.


  • Noise and free sound
  • Easy to setup and affordable
  • Efficient and cool amp performance


  • The sound is not that loud
  • The bass does not hit hard

The Importance of Speaker Impedance Load

Now that you know what impedance is, it is time to understand its importance. The impedance measurement of speakers is an average of the lower resistance it gives.

The impedance is always shifting; perhaps it will work with more than which. However, the 4 Ohms is the average of the lowest it is able to take.

Therefore, when the speaker is pressured to function at less than that regular consistency, this leads to overheating since the amps have been rated to supply power to the resistance offered.

Resonance Frequency

The resonance frequency is a frequency at which the speakers are not able to make any audio anymore. Once the given input signal from your amplifier is low for the speaker resistance, it gets into this frequency.

Here, speaker impedance will increase exponentially to meet electricity input from the amplifier. This can lead to your speaker overheating once it occurs too often. 

Voice Coils Inductance

The same as resonance frequency, voice coil inductance is when the voice coil inductors need to function at a higher frequency.

Once this takes place, there is an increase in the impedance to create the audio in accordance with the available frequency.

Is this related to the significance of impedance? Yes, as it means impedance isn’t necessarily a fixed measurement because it always modifies.

Electrical Resistance

A 4-ohm subwoofer offers four ohms of electrical resistance to the incoming amplifier signal. How many Ohms are a short? In technical terms, if there is a very low resistance in your car audio system, it can be an indicator of a short circuit or that one is about to happen.

Does Impedance Affect Power Output or Sound Quality? 

While a lot of speakers available have standard impedance ratings, you may need to understand how it changes depending on the equipment you utilize. If it has a higher impedance measurement; it will offer more resistance.

Therefore, you will need to search for low impedance if you need higher power as well as better sound quality. For instance, you have 200 watts RMS amplifier with 4 Ohms impedance.

In this case, you need a 4Ohms speaker to generate those 200 watts. On the other hand, if you opt for a 2 Ohms speaker, you will play 400 watts RMS and not 200 watts. Always bear in mind that a low-impedance subwoofer enables high passage of current and more load handling, leading to more power output.

This takes place as the speaker impedance rating is half the resistance of the 4 Ohms amplifier. Therefore, it enables the speaker to produce twice as much audio. It means that if the speakers impedance is low, more current will go into the system; therefore, if the load is higher, the higher the power it will make.

A speaker that has low impedance generates a higher current which translates into a louder sound than a speaker with a high impedance measurement.

Does 1 Ohm Impedance Offer A Louder Sound Output Than 4 Ohm?

After learning 1 Ohm and 3 Ohm systems, what really hits harder? If you need loudness and maximum bass depth, which one I will choose?

In which case, the obvious reason would be a 1 Ohm. A 1-ohm impedance load will hit harder and produce more output even if the total impedance is lower.

The sound will not be the neatest. However, the sound will be more than straight and respectable in most cases.

Sadly, you will perhaps encounter shut-offs as well as overheating, most particularly if you do not set up the right tools and equipment.

That is why we still suggest a 4 Ohm as the clearest and most stable sound. While you will not get similar volume capacity as well as bass delivery, still it is still a way better choice overall.


What do you want to accomplish? If you are searching for the right answer to the question of what hits harder 1 ohm or 4 ohm, then perhaps you will be somewhat puzzled as to what every impedance level provides. Amplifier and subwoofer specs are different, so make sure to be aware of this when upgrading your system.

We hope this guide can help you decide. This is not a simple subject to get used to; however, as long as you follow this guide and the information on this topic, you’ll learn precisely what you want on your audio system.

The one which hits harder is indeed the 1 Ohm subwoofer. On the other hand, is it worth it? Consider that prior to making a final option, and you will not regret it.
